Recent advancements have resulted in the application of PIP testing and analysis to the following metallic materials: • Brazed and nonbrazed Hardox steels used for mining applications[4] • Forged aluminum systems[5] • Fusion welds[6] • Residual stress quantification and e ects upon PIP data[7,8] • Quantification of creep characteristics[9] With the extensive PIP testing and analysis capabilities, the advanced materials and processing community is well positioned to benefit from this novel characterization method. ~AM&P For more information: Bryer C.
